BottomNavigationBarItem onPressed

The onPressed property in the BottomNavigationBarItem widget is used to specify the action that should be performed when the corresponding bottom navigation bar item is pressed.

The onPressed property takes a callback function as its value. This function is called when the item is pressed, allowing you to define the desired behavior or perform any necessary actions. It is commonly used to navigate to a different screen or update the UI.

Here is an example of how to use the onPressed property in a BottomNavigationBarItem:

    
      BottomNavigationBarItem(
        icon: Icon(Icons.home),
        label: 'Home',
        onPressed: () {
          // Perform action when Home item is pressed
          // For example, navigate to the Home screen or update UI
        },
      )
    
  

In the above example, when the “Home” item is pressed, the onPressed callback function is triggered. Inside the function, you can define the desired behavior, such as navigating to the Home screen using navigation methods like push, pushNamed, or update the UI based on the user interaction.
